Calling a function in bisect.m

I am not sure what is going wrong here, but I created a function @f. I am trying to implement it in bisect to find theta. When I am inside bisect, it says that there is an unrecognized function ot variable 'f'. Only that the function or variable is very much in the workspace when I am inside the function f.

Here is the complete code. hw7p2.m is the executable file.

Rashi - try removing (in the hw7p2.m file) the @ in front of the function handle that you are passing into the bisect function.

theta = bisect(f, pi/2, pi);  % <--- pass f and not @f

Also, consider removing feval from your bisect function and just do

fxl = fun(xl);
fxm = fun(xm);

Thank you so much. That solved it.
